Septic arthritis, Mycobacterium tuberculosis

Septic arthritis, Mycobacterium tuberculosis^[23]

1. Septic arthritis caused by susceptible Mycobacterium tuberculosis

1.1 Adults

Preferred regimen: Isoniazid 10–15 mg/kg (max: 300 mg) for 7 months AND Rifampin 10–20 mg/kg (max: 600 mg) for 7 months

2. Specific considerations

2.1 Pregnancy and breastfeeding

With the exception of streptomycin, the first line anti-TB drugs are safe for use in pregnancy: Streptomycin is ototoxic to the fetus and should not be used during pregnancy.
After active TB in the baby is ruled out, the baby should be given 6 months of isoniazid preventive therapy, followed by BCG vaccination.
Pyridoxine supplementation is recommended for all pregnant or breastfeeding women taking isoniazid.

2.2 Liver disorders

Two hepatotoxic drugs (rather than the three in the standard regimen):

9 months of Isoniazid AND Rifampicin AND Ethambutol (until or unless Isoniazid susceptibility is documented).
2 months of Isoniazid AND Rifampicin AND Streptomycin AND Ethambutol, followed by 6 months of Isoniazid AND Rifampicin.
6–9 months of Rifampicin AND [[Pyrazinamide}} AND Ethambutol.

One hepatotoxic drug:

2 months of Isoniazid AND Ethambutol AND [[Streptomycin}}, followed by 10 months of Isoniazid AND Ethambutol.

No hepatotoxic drugs:

18–24 months of Streptomycin AND Ethambutol AND a Fluoroquinolone.

2.3 Renal failure and severe renal insufficiency

The recommended initial TB treatment regimen for patients with renal failure or severe renal insufficiency is 2 months of isoniazid, rifampicin, pyrazinamide and ethambutol, followed by 4 months of isoniazid and rifampicin.
There is significant renal excretion of ethambutol and metabolites of pyrazinamide, and doses should therefore be adjusted.
Three times per week administration of these two drugs at the following doses is recommended: pyrazinamide (25 mg/kg), and ethambutol (15 mg/kg)
While receiving isoniazid, patients with severe renal insufficiency or failure should also be given pyridoxine in order to prevent peripheral neuropathy.
Because of an increased risk of nephrotoxicity and ototoxicity, Streptomycin should be avoided in patients with renal failure. If Streptomycin must be used, the dosage is 15 mg/kg, two or three times per week, to a maximum of 1 gram per dose, and serum levels of the drug should be monitored.

2.4 Previously treated patients in settings with rapid DST

TB patients whose treatment has failed or other patient groups with high likelihood of multidrug-resistant TB (MDR) should be started on an empirical MDR regimen.
TB patients returning after defaulting or relapsing from their first treatment course may receive the retreatment regimen containing first-line drugs 2HRZES/1HRZE/5HRE if country-specific data show low or medium levels of MDR in these patients or if such data are not available.

2.5 TB treatment in people living with HIV

TB patients with known positive HIV status and all TB patients living in HIV prevalent settings should receive daily TB treatment at least during the intensive phase.
For the continuation phase, the optimal dosing frequency is also daily for these patients.
If a daily continuation phase is not possible for these patients, three times weekly dosing during the continuation phase is an acceptable alternative.
It is recommended that TB patients who are living with HIV should receive at least the same duration of TB treatment as HIV-negative TB patients.
